Experiment for free, then go live and only pay for what you need. dotCloud enables developers and IT organizations to deploy, manage and scale their applications with unprecedented ease and flexibility by assembling and customizing powerful pre-configured stacks and services.

tsuru is an open source polyglot cloud application platform (PaaS). With tsuru, you don’t need to think about servers at all. You can write apps in the programming language of your choice, back it with add-on resources such as SQL and NoSQL databases, memcached, redis, and many others. You manage your app using the tsuru command-line tool and you deploy code using the Git revision control system, all running on the tsuru infrastructure.
